File Placement in a Web Cache Server
نویسندگان
چکیده
Web cache servers (proxies) are increasingly popular for reducing Internet traac and improving response time. The disk subsystem appears to be a bottleneck in such servers. We present techniques for improving disk performance of Web proxies and evaluate them with simulation. The disk workload of proxies has a signiicant volume of new le writes. We show that directing writes to less loaded disks improves disk load balancing and the response time. Also, partitioning disks further improves the performance by directing writes to selected partitions for reducing seeks. These techniques can be implemented at application level and do not require changes in underlying OS le system.

متن کاملDesign of an I/O Balancing File System on Web Server Clusters
The paper presents the design of an I/O balancing file system on Web server clusters. High-speed networks allow machines to access remote data nearly as quickly as they can access local data. This trend motivates the introduction of I/O balancing mechanism into cluster file systems. Two effective approaches are issued in the paper: file migration and unique cache. The former is to migrate the f...
متن کاملA Fast File System for Caching Web Objects
Given the increasing performance of network connections and the slow nature of disk drives, the authors propose a new file system for web proxy servers that cache files on a local disk. This file system, referred to as the cache file system (CFS), utilizes the facts that cached web pages do not change in size once they are cached, do not have changing permissions, and do have a back-up version ...
متن کاملCruz Efficient Data Distribution in a Web Server Farm
High-performance Web sites rely on Web server “farms”—hundreds of computers serving the same content—for scalability, reliability, and low-latency access to Internet content. Deploying these scalable farms typically requires the power of distributed or clustered file systems. Building Web server farms on file systems complements hierarchical proxy caching.1 Proxy caching replicates Web content ...
